Application filed May 25, 1923.

To all whom 2'25 may concern:

Be it known that I, ELMER DIAL, residing at Mill Run, Pennsylvania, a citizen of the 'more convenient and otherwise facilitate the operations of uniting the caps and fuses, it being necessary to attach to each cap a suitable length of fuse. My invention consists in whatever is described by or included within the terms or meaning of the appended claims.

In the annexed drawings:

Fig. 1 is a'vertical longitudinal section of an appliance or tool embodying my invention;

Fig. 2 is a bottom plan view thereof;

Fig. 3 is a bottom view in perspective;

Fig. 4 is a horizontal section on the line 4-4 of Fig. 1.

A device embodying my invention comprises, described briefly, a magazine for containing a number of caps side by side and a tool which besides performing such functions as cutting the fuse and splitting the fuse crimps the cap upon an inserted portion of the fuse to join the two in a firm and water-tight manner and means to control the delivery of one cap at a time to the tool for crimping the cap being automatically moved through the magazine to position for insertion ofthe fuse and crimping on the cap after such insertion.

The magazine. 10. comprises parallel side walls with a space between them to receive and support a row of caps which are cylin drical side by side and standing on end on the magazine bottom which is preferably covered by a sheet of rubber, 11, on which the open ends of the caps stand and the top of the magazine being a removable cover which may be a sliding cover, 12. the cover being removed when the supply of caps is to be replenished. In the magazine cap receiving space is a vertical, slidable follower block, 13, which by a suitable spring is forced from one end of the magazine to the other and resting in contact with the end cap of the row presses the row of caps TOOL FOR HANDLING BLASTING CAPS.

.through the magazine to the other end where in the bottom of the magazine is a hole, 14, through which the end of apiece of fuse to be attached to a cap is inserted and through which the attached fuseand cap may be withdrawn for use. The spring device for feeding the caps along may be a flat spring or as shown in the drawings it may be a coil spring, 15, encircling a rod, 16, to one end of which the follower block, 13, is attached and which passes through a guide lug, 17,- attached to an extension, 18, of the magazine bottom, said lug,'17,' forming a bearing for one end of the spring, 15, the other end of which presses against a suitable shoulder on the rod, 16, to move the rod and follower, 13.

The end one of a row of caps in the magazine is pressed by the spring feeding device against a cap stop which consists of a block, 19, that is mounted to slide transversely of the magazine and on the side to wards the cap has a notch or slot 20, which by sliding the block to one position alines with the end cap so that the latter may enter the slot and when the stop is permitted to move in the opposite position or is moved in the opposite position as by a coil spring, 21, the cap stop forming portion, 22, of the block will lie between the cap in the slot and the next following cap so that the pressure from the spring will not fall upon the cap in the slot and feeding of the remaining caps in the magazine will not take place. The cap thus trapped in the slot, 20. will be ready for easy removal through the hole, 14, after the piece of fuse has been joined to the cap.

The cap trapped in the slot, 20, will have its lower open end in alinement with the hole, 14:, and the end of a piece of fuse may be passed through the hole, 14, and thrust in the open end of the cap. fter that has been done the cap is crimped between two jaws one a stationary jaw. 23, and the other a movable jaw, 24, since it is on a handle, 25, pivoted to the magazine at the bottom, the two jaws having opposed concave faces whose arcs are of less radius than the diameter of the cap so that when the jaws are brought together upon the fuse containing a portion of the cap, the cap walls will be snugly crimped upon the fuse.

The two jaws, 23 and 24, are on diametrically opposite sides of the hole. 14;, and the movable jaw has an extension, 26, towards the other jaw which forms a stop for uhe lower end of the cap, and is in position to engage the lower end of the cap when the movable jaw, 24:, is moved away from the stationary jaw to allow the entry of acap into the slot, 20, of the cap stop, 19, the handle, 25, being moved for this purpose preliminary to placing a cap in position for insertion of the fuse. A handle like extension, 27, of the bottom of the magazine is provided along side the handle, 25, for the-proper manipulation of the latter for crimping. The'bottom of the magazine and the handle, 27 are preferably made in one piece of sheet iron and a sheet of steel, 28, which is welded to the inner side thereof. lhe side walls of the magazine may be of sheet iron lined with rubber or wood.

What I claim is:

1. A magazine for caps having an outlet hole and means for crimping the walls of a cap upon an inserted fuse adjacent said hole.

2. A magazine for caps having an outlet hole and means for crimping the walls of a cap upon an. inserted fuse adjacent said hole, comprising handles and coacting jaws.

8. A magazine for caps having an outlet hole and means for crimping the walls of a cap upon an inserted fuse adjacent said hole, comprising handles and coacting jaws, one of such handles being a prolongation of the bottom of the magazine in which such hole is located 4. A magazine for caps having an outlet hole and means for crimping the walls of a cap upon an inserted fuse adjacent said hole, and means to effect the separation of one cap to be operated on' from others in the magazine.

5. A magazine for caps having an outlet hole and means for crimping the walls of a cap upon an inserted fuse adjacent said hole, and means to effect the separation of one cap to be operated on from others in the magazine, comprising a slide having a cap receiving slot.

In testimony whereof I hereunto aiiix my signature.

ELMER DIAL.
